> @Andre Eikmeyer I think this patch should fix your system as well. Hi Alex, I guess you have seen it already but the patch doesn't match the 16,1. Its boards are 7340/020f and 7340/0210, and v4 only matches 0218, 0219 and 021a. That hang is what I sent a fix for https://lore.kernel.org/all/[email protected]/ The VBIOS trains the UMC p-states at different frequencies the pp-table lists. The SMU hangs as soon as UCLK switches into level 2. Deferring the UCLK enable doesn't change the levels, so the hang just moves from boot to later under load. The two patches can coexist after a trivial rebase. > ...your system... I need to clarify here. I actually don't own a 16,1. But I maintain a distro (KaiT2en) that specializes on T2 Macs. So the patches I develop are extensively tested by the community before submitting. Atharwa is part of this community. Ed is not, but Atharwa reviewed and tested the code. Best, Andre
